Why flagged

The package builds from source hosted on GitHub (project's own repository), and the additional SDK download from a non-whitelisted host (cdn.hush.umceko.com) is a prebuilt library required for linking; while the host is non-standard, it is plausibly project-specific and used for distribution of a binary dependency, not remote code execution.

Triggered rules

Low AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-2507) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package builds from source hosted on GitHub (project's own repository), and the additional SDK download from a non-whitelisted host (cdn.hush.umceko.com) is a prebuilt library required for linking; while the host is non-standard, it is plausibly project-specific and used for distribution of a binary dependency, not remote code execution.

1 higher static finding superseded - not the current verdict (shown for transparency)

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
